I really need some help with this question

Answer:

6.2

Step-by-step explanation:

[tex] \frac{7.2 + 7.6 + x}{3} = 7.0 \\ \frac{14.8 + x}{3} = 7.0 \\ 14.8 + x = 21 \\ x = 21 - 14.8 \\ x = 6.2[/tex]

84= 28×3

28=4×7

4= 2×2

600= 50× 12

50= 25x2 12=3x4

25=5x5 4=2x2

hope it will hepl :)

Answer:

have you been cheating and your answer i think is number 3

Step-by-step explanation:

The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method

The given equation is  [tex]\frac{x}{3} + 8 = -2[/tex]

Solving the equation using Natasha's method

the fist step is to multiply by 2

x + 24 = - 6

The second step is to combine  and add similar terms

x = -24 - 6

x = -30

Second method of solving the equation

The equation the friends are trying to solve is [tex]\frac{x}{3} + 8 = -2[/tex]

The first step is to combine similar terms

[tex]\frac{x}{3}[/tex] = - 8 - 2

The second step is to add similar terms together

[tex]\frac{x}{3}[/tex] = - 10

The third step is to multiply both sides of the equation by 3

x = (-10 x 3)

x = -30

Answer:

[tex]112\pi[/tex]

Step-by-step explanation:

hi! for this problem, all we need is the equation for the SA for a cylinder!

here's the equation: [tex]A=2\pi(r)(h)+2(\pi)r^{2}[/tex]

BUT FIRST let's identify our given numbers

now all we have to do is plug in what is given to the equation above! not so bad, right?

plugged in equation

[tex]A = 2\pi (4)(10) + 2\pi (4)^{2}[/tex]

- now let's simplify!

[tex]2\pi (40) + 2\pi (16)[/tex]

[tex]80\pi + 32\pi[/tex]

[tex]112\pi[/tex]

your answer should be [tex]112\pi[/tex]

Answer:

4.) Cost of cordless phone = $55

cost of each additional handset = $25  

Therefore, the overall cost of the cordless phone, including the 3 extra handsets is:

$55 + 3($25) = $55 + $75 = $130

5.) Given the function, f(d ) = .20d + 14, where:

f(d) = global temperature (in Celsius)

d = number of decades  

To evaluate the value of f (d ) at f(10), you'll have to substitute the value of d = 10 as input into the function:

f(10) = .20(10) + 14

f(10) = 2 + 14

f(10) = 16

6.) Value of f(10):

    In 10 decades, the predicted global temperature will be 16° Celsius.

7.) The correct answer is B. The global temperature f(d) depends on the number of decades, d.

Explanation: the independent variable is d →  it is the input of the function. The output primarily depends on the given value of input.

8.) Given the function, f(t ) = 0.2t

where t = represents number of days elapsed since the planting of the seed.

         Evaluate f(40):

        f(40) = 0.2(40)

        f(40) = 8

Answer:

C

Step-by-step explanation:

The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

The rate of change is also known as slope. The slope of a linear function or a line is

It is given that the function 1 is passing through the points (0,3) and (4,3). Slope of function 1 is

Therefore the slope of first function is 0.

The slope intercept form of a line is

Where, m is the slope and b is y-intercept.

The second function is

Therefore the slope of second function is 2 and the y-intercept is 1.

The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

Answer:

ok well I think it is 16

Step-by-step explanation:

because the parentheses first 2 x 2 x 2=8

then we have the outside of the parentheses 2, 8x2=16

so I think the answer is 16

Let's see

So

[tex]\\ \rm\rightarrowtail 2^{3(2)}[/tex]

[tex]\\ \rm\rightarrowtail 2^6[/tex]

[tex]\\ \rm\rightarrowtail 64[/tex]

You get a third of some number x if you divide x by 3.

So, one third of (1/3)⁸ is

(1/3)⁸ / 3 = (1/3)⁸ × 1/3 = 1/(3⁸⁺¹) = 1/3⁹

Answer:

12 and (-12)

Step-by-step explanation:

Solve for x.

x^2= 144

square root both sides and get,

x= 12

and

x= (-12)

remember to put your negative and 12 into parenthesis because you are multiplying the negative as well.

Answer:

x = 12

x = -12

Step-by-step explanation:

Step 1: Take the square root of both sides.

Therefore, x = 12 and x = -12 are the answers.

Answer: 7/24 is the answer to this question

Answer: x = 7

Step-by-step explanation:

5x + 7 = 42

We then take 7 away from both sides:

5x = 35

Then, we need to make it so x = answer. To make 5x into x, we divide by 5 meaning that we next need to divide both sides by 5.

x = 7

Using normal distribution table, the area between z=0 and z=1.70 is the difference between p(z=0) and p(z=1.70). Hence, the area between z=0 and z = 1.70 is 0.4554

Using a normal distribution table :

The Area between z=0 and z= 1.70 is defined as the difference between the probabilities of (z < 1.70) and (z < 0)

P(Z < 1.70) - P(Z < 0) = 0.95543 - 0.5 = 0.45543

Therefore, the area between z = 0 and z = 1.70 rounded to four decimal places is 0.4554
